Objective To investigate the different ability to produce H_(2)O_(2+) of the vaginal lactobacilli and their potential antagonism toward E.coli in ivtro.Then to select the potential lactobacilli strain to treat the female urogenital infection.Method To detect production of H_(2)O_(2) by measuring the blue matter in water solution with absorbtion spectrophotometry.The lactobacillus and E.coli were cultured together in solid culture medium,followed by the measurement of inhibition zone around the lactobacilli after 24 hour.Results We selected 4 strains of lactobacilli from vagina.L.acidophilus1 and L.paracasei3 are the stronger to produce H_(2)O_(2).The largest diameter of the ring of inhibition is shown around the lactobacilli acidophilus 1.Conclusion The lactobacilli acidophilus 1 and lactobacilli crispatus are the most potential strains as antagonist to E.coli and their antagonism depend not only on lacid or H_(2)O_(2).

Polo-like kinase 1 (PLK1) is a highly conserved serine/threonine protein kinase that has attracted research attention be-cause it plays a critical role in mitosis regulation. PLK1 is overexpressed in 80%of human tumors, which indicates a poor prognosis in most tumors. PLK1 is one of the most promising targets for antitumor therapy because it is upregulated in castrate-resistant prostate can-cer (CRPC). This review focused on the basic structure and function of PLK1, the relationship between PLK1 and CRPC occurrence and progression, and CRPC treatment by inhibiting PLK1. This study provides a theoretical basis for the targeted molecular therapy of CRPC.

To investigate the psychological difference in abdominal aortic aneurysm patients before and after operation and its influence on life quality, 24 patients who can understand and complete the questionnaire were enrolled in the study, the inquiry was performed after admission and discharge with the standard SCL 90 table. The results showed that the general conditions, depression, anxiety, compulsive symptoms and fear of the patients had marked differences before and after operation. It is concluded that operation of abdominal aortic aneurysm can not only prevent the rupture of aneurysm but also relieve the patients′ psychological pressuer and improve their life quality.

BACKGROUND:Basic fibroblast growth factor (bFGF) can enhance fibroblast proliferation and col agen deposition, and vascular endothelial growth factor (VEGF) can improve blood perfusion and metabolic level of pathological tissues. Additional y, both of them can boost the alkaline phosphatase activity under given conditions. OBJECTIVE:To evaluate the effect of bFGF combined with VEGF on the periodontal ligament fibroblast proliferation and alkaline phosphatase activity in rats. METHODS:Rat periodontal ligament fibroblasts were cultured in vitro, its embryonic origin was identified and passage 4 cel s were used for the fol owing experiments. Effects of bFGF and VEGF with different concentrations on the rat periodontal ligament fibroblast proliferation were detected to determine the minimum and maximum effective concentrations. Cel s were divided into five groups:group A (control group) with DMEM containing 2%fetal bovine serum;group B as maximum effective concentration of VEGF group;group C as maximum effective concentration of bFGF;group D as minimum effective concentration of bFGF combined with minimum effective concentration of VEGF group;group E as maximum effective concentration of bFGF combined with maximum effective concentration of VEGF group. At 3, 7 and 14 days, the alkaline phosphatase activity in each group was detected. RESULTS AND CONCLUSION:Rat periodontal ligament fibroblasts derived from the mesoderm grew wel . Rat periodontal ligament fibroblast proliferation was increased with the VEGF and bFGF concentration increasing (P<0.01). The maximum and minimum effective concentrations of VEGF were 100 and 10μg/L, and the maximum and minimum effective concentrations of bFGF were 10 and 0.1μg/L. The absorbance values in the groups D and E were higher than those in the group A. The absorbance values of the group D were significantly lower than those of the group E at 3 and 7 days (P<0.05), but did not significantly differ at 14 days (P>0.05). To conclude, the combination use of the maximum effective concentration of VEGF and bFGF can play a significant synergistic effect on the alkaline phosphatase activity at a given time, but the minimum and maximum effective concentrations show no significant differences if not in the given time, which may be related to the time-effectiveness of these two factors and the receptors of periodontal ligament cel s.

Objective To explore the impact of resilience and anxiety, depression on quality of life (QOL) among esophageal carcinoma patients undergoing radiotherapy and (or) chemotherapy. Methods A total of 125 patients were recruited into our study. Date were collected by European Organization for Research and Treatment of Cancer, Quality of Life Questionnaire-Core 30 (EORTC QLQ-C30) , Resilience Scale (RS) and Hospital Anxiety and Depression Scale (HADS). Analysis of Moment Structures (AMOS) version 7.0 software was used to conduct the path analysis. Results The total score of patients′ QOL, RS and HADS were(51.98±19.42)points,(56.32±17.09)points,(14.59±7.04)points. Pearson′s analysis showed that QOL was correlated with RS and HADS ( r =0.423-0.588,P<0.05). RS was negatively correlated with HADS (path coefficient was-0.76 and-0.37) and HADS negatively correlated with QOL (path coefficient was-0.56 and-0.79). RS as a protective factor indirectly influenced QOL via HADS and the paths′ total coefficients was 0.69. Conclusions The level of QOL and RS were at poor level for esophageal carcinoma patients, as well as participants experienced anxiety and depression. HADS as intermediary variable has a greater moderating effect on relationships between RS and QOL. RS is a indirect protective factor of QOL. Interventions developed on the basis of influencing factors of QOL should be applied to improve patients′integral health status.

OBJECTIVE:To analyze the cost of three schemes in treatment of unstable angina pectoris METHODS:88 patients with unstable angina pectoris were divided into three groups:group Ⅰ was given isosorbide,asprin,nifedipine and nitroglycerin;group Ⅱ was given isosorbide,asprin,nifedipine,nitroglycerin and red sage injection and group Ⅲ was given isosorbide,asprin,nifedipine,nitroglycerin and puerarin;then using pharmacoeconomic method,cost-effectiveness analysis was carried out RESULTS:The efficacy in the group Ⅱ and group Ⅲ was higher than that in group Ⅰ(P0 05),and the E/C(effectiveness/cost) of the three groups were 15 98,18 02 and 33 40 respectively Compared with group Ⅰ,?C/?E of group Ⅱ and Ⅲ were 24 66,83 90 respectively;Compared with group Ⅱ,?C/?E of group Ⅲ was 643 60 CONCLUSION:The scheme for group Ⅱ is the best one

Objective To evaluate changes and clinical significance of products of hurted endothelium in pregnant women with hypertensive disorder.Methods The levels of tissue factor(TF),tissue-type plasminogen activator(tPA),plasminogen activator inhibitor(PAI),von Willebrand factor(vWF) were determined in 87 pregnant women with hypertension as well as in 100 normal pregnant women and 100 normal nonpregnant women.Results The levels of TF,PAI and vWF were higher in pregnant women with hypertension than in normal pregnant women and nonpregnant women(P0.05),but the contents of tPA in these two groups were significantly higher than that in normal nonpregnant women(P

Objective To investigate influences of paeonol on mRNA expression and function of drug transporters BCRP and SLCO1B1 in HepG2 cell.Methods Cell counting Kit-8 assay was used to detect the viability of HepG2 cells;Real-time fluorescent quantitative PCR (qPCR) was performed to measure the expressions of BCRP and SLCO1B1 mRNAs; flow cytometry was applied to determine the transport functions of BCRP and SLCO1B1. Results Paeonol (2-8μg/mL) did not decrease HepG2 cell survival rate, but 16 μg/mL paeonol significantly reduced cell survival rate (P<0.05). Paeonol(2-8μg/mL)significantly induced the mRNA expression and function of drug transporters BCRP and SLCO1B1(P <0.05).Compared with control group, transcription level of paeonol group’s BCRP and SLCO1B1 drug transporters obviously up-regulated, the of translocation efficiency of substrate specificity increased significantly (P <0.05).Conclusion Paeonol can induce drug hepatocellular transporters BCRP and SLCO1B1 gene expression, thereby promote the substrate transport the transmembrane.It is indicated that the drug combination of paeonol and BCRP and SLCO1B1 transporters, there may be a risk of drug interactions.
